SHELL.

Specification of Letters Patent.

Patent-ea June 12, 191'?.

Application filed January 21, 1916. Serial No. 73,325.

To all whom t may concer/n Be it known that I, JOSEPH PAIL, J r., asubject of the King of England, residing at Prague, Alberta, Canada,have invented a new and useful Shell, of which the following is aspecification.

This invention relates to explosive shells or projectiles and has forits object the provision of a novel and improved triple action shellwhich can be used not only as shrapnel but also, as a grenade.

It is also within the scope of this invention to provide a veryefficient shell, simple and inexpensive in construction.

With the foregoing and othervobjects in View which will be apparent fromthe illustrations and description, the present invention findsembodiment in the novel combination and arrangement of parts and membersand in the details of constructionherein shown, described and moreparticularly pointed out in the appended claims.

An illustration of my invention is found in the accompanying drawings,wherein Figure 1 is a longitudinal section of a shell constructedaccording to my invention; and

Figs. 2 and 3 are cross sections, taken respectively on lines 2 2 and3-3 of Fig. `1.

Fig. 1 is an elevation of the bomb in the lower or base chamber.

The shell comprises a cylindrical wall 5 cast with a partition ordiaphragm 6 which isY dished or concave on both sides and provided witha small central opening lfor the short connecting fuse-tube 7 One end ofthe cylinder 5 is screw-connected with the head 8 which may have bothtime and percussion fuses whereby the shell may be set off or fired at acertain time or distarce from the projecting ordnance or shotas agrenade.

I have preferred to illustrate herein a time-fuse constructioncomprising a hammer 9 carrying a primer 10 which is forced by the setback to strike the point '11 of the anvil 12 and cause a flame to travelby the time-ring 13 and channel 14 to a highly eX- plosive charge 15held within the head 8 by a disk 16.

The impact or percussion-fuse comprises a 1 rimer 17 held Within anvil12 and adapted for detona'tion by the momentum of the pointed hammer 18,causing the igniting flame to pass through port 19 and passage 14 toignite charge 15.

Before affixing the head 8 to cylinder 5 a charge-disk 20 of paper orother very thin and inflammable material filled with a high explosive,or charge and having oppositely bulging convex sides 20A, conforming tothe curvature of the diaphragm and with flattened edges 20B, is placedon theA dished diaphragm 6 so lthat the projecting fuse-tube 7perforates the charge-disk 2O to afford communication with a similarcharge disk 21 on the other side of the diaphragm 6 in the base-chamber.

A castiron disk 22 is neXt placed on top of the charge-disk 20. Thisiron disk 22 has a curved side arranged to fit over the side 20A of theAcharge-disk 20 and the flattened edges 20B against the diaphragm 6.

A thin tube 23 having a supporting shoulder 23A, containing'a quicklyignitible fuse, is neXt inserted into the small central opening of disk22 to perfor-ate the charge disk 2O and rest shoulder 23A on topthereof.

vAfter the balls or shot 24A are filled in vscrew connection therewith,the 4complete bomb member 26 is inserted 'to confine the charge 21 in asimilar manner to the disk I22 in the upper chamber.

The large balls or shot 24B are then filled in around same.

with an explosive 29 is secu rely held against the head by means of thescrew 28 carrying a time fuse which acts to communicate the ignitionfrom charge 21 to charge 29. The charge 27 being lled through the rearend which is provided with a screw connected back 27 A. A quantity ofsmall balls or shot 30 are filled in between 'the charge 27 and interiorof body 26B.

Several small pyramids, 26D, or the like may be cast on the exterior ofthe body 26B, to confine the bomb to a relatively central positionwithin the base chamber.

After the shell is shot from the projecting piece of ordnance, the timefuse will phragm 6 and the disk 22 and bomb head '26A the two chargescommunicating through the ordinary opening` in the center of thediaphragm.

Likewise various other simple changes may be made in fthe constructionof the vari- `ous members without departing from the spirit of myinvention.

" I claim as my invention:

1. A triple action shell comprising a head chamber, a base chamber, anexplosive *charge and shrapnel balls in each chamber and abomb in thebase chamber, said bomb having an independent explosive charge incommunication with the explosive charge of Athe basel chamber, saidcharges and bomb arranged for successive explosion.

2. A triple action shell comprising a head chamber, a base chamber, anexplosive charge and shrapnel'balls in each chamber, and a bomb in saidbase chamber, said bomb having an independent explosive charge incommunication Iwith theexplosive charge of the base chamber, saidcharges and Ybomb charge arranged for successive explosion `and saidcharges being adjacentand interconnected.

3. triple action shell comprising a cylindrical body having a diaphragmwithin dividing the interior into a head chamber and a base chamber, anopening in said diaohravm an ex ilosive charge on eachside of saiddiaphragm, said charges communicating through said opening, shrapnelballs in said chambers, a bomb in lsaid base chamber, said bomb havingan independent ex plosive charge incommunication with the explosivecharge of the base chamber, said charges and bomb arranged forsuccessive explosion.

v t. A triple .action shell comprising a cylindrical body, a diaphragmwithin said body dividing the interior thereof into head Vand Ybasechambers, an opening in said diaphragm, explosive charges on both sidesof said diaphragm, said charges communicating through said opening,shrapnel balls inV said chambers, a bomb in said base chamber having anindependent explosive charge directly communicating with said explosivecharge in said base chamber, said charges and bomb arranged forsuccessive explosion.

5. A triple action shell comprising a cylindrical body and a fuse-headtherefor, a diaphragm within said body dividing the interior thereofinto a head chamber and a Vbase chamber, said diaphragm having concavesides and a concentric opening therein,

yan explosive in each concave side, said "charges communicating throughsaid opening, a convex disk forming a cover for said charge in the headchamber, shrapnelballs between said cover and fuse-head, a quicklyactingfuse connecting said use head with said charge in said head chamber, abomb having a concave head adapted to house said charge 'in said basechamber, `an explosive charge in' said bomb communicatingvwith saidcharge in said base chamber, shrapnel balls on the exterior of said bombin said base chamber, and shrapnel balls within r'said bomb, saidcharges in said chambers and charge in said bomb arranged for successiveexplosion.

6. A triple action shell comprising a cylindrical body and a fuse-headtherefor, a diaphragm Within said body dividing the interior thereofinto a head chamber and a base chamber, said diaphragm having concavesides and a concentric opening therein,

an explosive in each concave side, .said

charges communicating through said opening, a convex disk foi-ming acover for said charge in the head chamber, shrapnel balls .between saidcover and Afuse-head, a quicklyacting fuse connecting said fuse headwith `said charge in said head chamber, a bomb adapted to house saidcharge in said base chamber, an explosive charge in said bombcommunicating with said charge in said base chamber, shrapnel balls onthe exterior of said bomb in said .base chamber, said charges in saidchambers and charge in said bomb arranged for successive explosion.

In witness .whereof I have hereuntol afiixed my signature this 13th dayof January A. D. 1916. f
